edited as i got the info all wrong !!
tw2800 is cut down version to ( 6100/tw3800 - us model)
havent found any reviews on the tw2800 however
http://www.premierehomecinema.co.uk are doing a deal on the tw3800 at the mo.
bear in mind tho the pt-ae3000 is comaprable to the tw5000 ( 6500ub) and can be had for about 2k and is significantly better than the tw3800 as reviewed by projectorreviews.com.
I would advise to pick a budget and stick to it. esp in the current economic climate. I just wish i could take my own advice!!
im tempted by the tw2800 myself - dont believe anyone does epson PJ demos in our region though.
