All of my tanks came from walmart. That includes a 55g with the walmart stand, and a 29g with their stand also. The tanks are perfectly fine and I've never had a problem with them. No leaks, good siliconing job, etc. The stands are more than sturdy and rather attractive, IMO. The 55g stand has 4 frontal cabinets which are handy. The 29g stand is a bit taller than the 55g's and has 2 frontal cabinets. Both are black vinyl, I believe.
I still use the original filters and heaters that came on all the tanks except the 55g. I've got 4 of their 10g's (metal double stands) and 4 of their 5'gs. I really like the filters that came in the 10g kits.
The lights/hood that comes with the 55g is perfect for a fish-only tank.
I upgraded the filter on the 55g to a Fluval 304 and replaced that heater only because it malfunctioned (though all of my other heaters still work fine, I think it was a fluke).
55g tank, lights, their filter and heater, net, and stand, cost 250$.
