OP back, tried the MeshForce system and it solved the distance issue of lower speeds at far ends of house, but the overall speed was lower!
One spec I didn't catch was the 100Mb limit on the WAN port. That's a very important figure, with my fibre optic to the house and a 400Mb cap I was losing 300Mb of speed. It doesn't matter that the nodes talk at 'fast' if your max through put is only 100Mb.
MeshForce will be coming out with a 1G WAN port soon and I'll be looking at that when it does. The system itself was easy to setup and configure and the seemless max wifi speed through out the house was nice.
