If you're happy with 2nd hand, then I can recommend the Markbass CMD102p combo. One of the loudest, lightest & best sounding combos I've ever played through & it's never let me down.
The amp section is a Little Mark II (or III if you go for a newer one), so adding another cab is no probs & it has an fx loop that can be pre or post (one position mixes it with your dry signal).
They usually pop in the For Sale section on here for @ £600 (they're @ £1k new).
Like Prime bass says, there's plenty of decent kit in your price range, better quality stuff if you go down the 2nd hand route.
I can understand you being interested in the TC gear, but Marshall? Unless it's their older gear, the only thing that intrigues me about them is why are they still making crap bass gear?
