I own a Gazelle freestyle, and I love it! Depending on how old the machine is, either one could have the computer on it or not, the one that gauges distance, calories burned, heart rate monitor, etc. But even without one, it's a great workout. I like it because it is a no impact exercise machine, which is great for anyone with bad knees or ankles. It's a good cardio workout. It folds up flat for storage.
Also, I don't know how much you are paying for it, but if it's not the freestyle, the regular models are fairly cheap now-less than $100.00. I paid $250 for my freestyle on sale (it was regular $350 at the time).
I can't really say for sure about the weight limit, but they are very well built, so my guess would be that the extra 25 pounds won't be that bad.
The only complaint I have about the machine is that after about 6 months of use the cables and connectors starting squeaking when I used them, but a little oil fixed that, so it's not a serious complaint anyway.
You say it's super cheap-I would jump on it! It will be a great way to "come back from vacation". The cardio may be just what you need to come through that standstill!
