Hiya norky, as far as I have gathered the Juwels are very nice tanks. Everyone raves about their build quality. Yeah, I don't like the built in filter and did take mine out, it's easily done if you feel the same. Regarding the price, you can probably get it for a little cheaper. To take the hard work out of searching for a tank on ebay set up a search for tanks that only shows you what is within ## miles of your post code (the option is lower down on the left side) then save the search and tick the box to have it send you email alerts when things match your search. I think that option is just under the search bar.
It may take a few weeks before a real bargain pops up but used tanks are being sold all the time I'm sure one will come up
