Schumacher stockists? Looking for a Cat SX S1

[jimmiprice]

Guys im after a new 10th car, changing from a B44 and im looking for a cat SX. Probably going to get one of the S1 models, it will suit the little bit of indoor racing i do. Is the only difference the change from CF and the steel turnbuckles ? Also has anyone got any good starting setups for running on polished floors.
Main problem i can find is that noone seems to be stocking the S1 apart from modelsport who are pretty expensive. Can anyone point me in the direction of a good schumacher dealer, somewhere online would be better.
Thanks.......
