Shower tray with legs

[wiggers]

Ok chaps after some advice got a job fitting a 1200mm x 900mm tray I'm looking to put it on legs saving me time and effort I normally put on ply and build base up but now looking for the strongest one to use are the mira trays any good or can you guys recommend any don't want any wobble maybe there are screw in types around
thanks lads

I've fitted a few different types and find the best way to avoid wobble is to ignore the legs adjacent to the wall and batten. Then stick the tray in place using adiseal or similar. If I've any doubt I also put a couple of bags of sand in the tray and fill the gap with squirty foam, leaving access to the trap.
