I was waiting for LM4 mags to come in stock before buying a KWA. Having seen these new TMs I'm in half a mind to hold of and wait. The GHK isn't far off either I don't think
I, like you was eyeing up the LM4 or GHK offering (even considering a WE with some RA Tech bits), no way now, I'll wait as long as I need to for the TM one. If it's even 2/3 as good as the GBB MP7 it'll be the best OOTB GBBR on the market.
