If you are looking at the R5.2 it really isn't a bad machine for the money. I would recommend that you buy something from Proform or NordicTrack first but if this is all you can afford then OK.
Let's face it, Weslo makes crappy elliptical machines. If this is all of the money that you can afford you will be better off purchasing a gym membership at one of those $20 per month clubs I see all over the place these days. It's not that the machine is bad for the money, in that respect it's fine. It's just that you can't build and sell and elliptical that has decent quality in the price ranges that Weslo sells them at.
