Hi Ty,
We train on jig-mats at Tuesday class in a church hall. (Friday class at the sports centre we have tatami and a canvas).
They're pretty good, have lasted many years (we got them 2nd hand) and the only problem has been that if you don't take them up carefully the little 'bobbles' along the edges can tear off.. we just keep ours in a bag and plug them in the gaps!
Also, decide carefully if you have a colour choice, as these mats are not brilliantly colour-fast and may stain your feet or clothing, so go for something lighter coloured if you can
