Right now I have a 65 from glass cages set up. I'd probably not recomend them for an acrylic tank. It seams like they just slapped it together with out much thought of quality or craftsmanship. The 65 from GC is a fairly good tank though just built with molding from glass tanks which I do not like. The 150 I just got not to sure who the maker. I see these 150's on ebay alot sold new.

Scratches are pretty easy to take care of with a buffing cream for acrylic. Both of my tanks I bought used from other hobbiests. There are some pros and cons to acrylic though that I have found. I'll list them after work tonight for you.
