My stationary bike started to show its age (age 6, it's ready to go to school now... I mean, to travel home to my parents for a lighter use and more loving than I can give it), and I'm thinking about investing into a new one. However, I'm having second thoughts about it, and it's really tempting to buy an elliptical instead.
I enjoy working out on both, I loved the elliptical when I used to go to the gym. Tho I liked nearly all the stuff there, even the treadmill, so from enjoyment point of view they are equal to me. But as I'm not a fitness expert and I'm about to invest some serious money into it, I thought I'd ask for advice about it. Should I get the elliptical or the bike? What should I keep in mind when choosing one, any advice about that? Also, does anyone has experience with buying a used bike/elliptical? Is that worth it or should I get a brand new one, even if it costs a lot more?
I exercise 3-5 times a week for one hour. I'm 5'4, 113 lbs, so I don't do it to lose weight, just to keep me happy and in good condition. Okay, a bit of toning would be nice, as I lost 30 lbs since May 2011 and maintaining my current weight since November, I still have some fat left to turn into muscles. 
So, any advice? 
Ellipticals tend to burn more calories than the stationary bike, but since you are not looking to lose weight, you should buy the one you prefer.
If given the choice, I would go with an elliptical. I like something that burns calories at a faster pace. I've also heard (no citation sorry) that sitting down to exercise (bike) doesn't provde as many benefits as standing exercise (I think it's in NROL).
But if you like the bike then go for it. One benefit is that it's easier to read while you pedal!
I can't see spending good money on a stationary bike.. For the kind of money they run I'd rather just get a really nice used bike and a mag stationary trainer then you have something you can use outdoors too...And I like cycling, but hate exercise bikes myself.. I'll go ride 15-20 miles on my bike in an hour and a half, but can't seem to ride a stationary for more than 15 minutes before I get sick of it.
But I will do an elliptical without much griping... If its a decent one.
Elliptical. Honestly, stationary bikes are a huge waste of time. It's very hard to get your heart rate up, they are not very good for your knees unless you are fully extending your legs, and it only works out your lower body, and some abs. Also, it's a stationary bike... get on a real bike! It's a lot better workout and a lot more fun too. Also, you can get a good bike for under 100. I recommend you look for a good elliptical used first, because then you can get a higher quality model. There are bad ellipticals, so be weary.
Thank you for the replies, everyone!
I own a real bike too, so don't worry about that part, tho it's a bike for off road use, I prefer that over biking in the city. Sadly, I live in a large city, so I can't go on off road trips as much as I would prefer. I used to live in the countryside and had the opportunity more often, but I had to move because of my job. That's when I got my stationary bike to have some poor substitute, I was going mad without being able to bike a lot! Hopefully it won't be an issue if I go for an elliptical instead.
@kevinatthebrook: I can't read while biking. I read too fast so I finish magazines halfway in my workout and I can get way too lost in books and then I forget to bike and just read on, sitting on the bike. 
I usually "watch" TV show streams that don't require much attention, but keep me from getting bored on the bike.
So basically getting a used, but good quality elliptical is better than going for a cheaper, but new one? I can scrape together the money for getting a new Robust, maybe even a NordicTrack, but as I've never bought an elliptical before, I don't know how important it is to buy brands.
