We bought an Octane Q something five years ago and loved it. I'm 240lbs and the thing didnt move when I got rockin on it. It was in the $1250 range new. And I think it was about 350 lbs. One suggestion is to really manhandle whatever you are testing out at the store. Try to make it rock, rattle etc...
I don't have a suggestion for a speciic elliptical. I would check out the reputable used exercise equipment places near you, though. They may be more expensive than Craigslist, but they may also offer some type of warranty. And do so before mid-December so you can beat the New Years Resolution group.
We have the Sole E35 and its great. It doesnt have fancy displays or crazy settings or anything like that; its all metal and solidly built. We've had it for 3 years now and never have had an issue with it. I did a lot of research before buying and they always seemed to be in the conversation. Not cheap, and my recommendation is to buy to your limit (that's what we did rather than compromise). They outfit Hilton Hotels I believe. Just a little bit of maintenance (mainly cleaning and lubing up the tracks) and haven't ever had a problem with it.
I liked them so much we bought a treadmill from them and that thing is great.
An elliptical costs a lot less than knee surgeryDecent pair of running shoes, shorts and a shirt cost a lot less than an elliptical.

I bought a used Octane (lower end health club model) about 4 years ago and it's fantastic. It weighs a ton (I think the crate it came in said 400 lbs) and when I do intervals on it the thing is rock solid. I looked at some "nice" ones in the stores, but they all felt cheap and "rickety" by comparison. The ones made for health clubs and gyms are a LOT more rugged than the ones made for Sears or Dick's. I was lucky to get an in-house demo model directly from Octane so it really didn't have many miles on it and was fully refurbished.
If you plan on using it in your basement (low ceiling) make sure to check the step height so you're not ducking to use it.
on top of that, make sure you have a couple of burly buddies to move it. I thought I was going to end up in the hospital when we hauled ours out of the basement. Beats a cheapie that comes undone right underneath you though.
