They will hold - an if 150£ is your budget, then I don't see any real bargain alternatives to the 32spoke sealed bearing Miche.
Halo Aerowarrior would be worth the extra if you want ready built wheels, but you should be able to do Rigida Grizzly on Novatec for less. £45 for hubs, £34 for rims, £30 for spokes, £10 for nipples, and it's a nice easy build to start with even if you don't habitually roll your own.
