Welcome to SRP Alakuu

one of the razors sold already both seems to be good deals

A brush that works is all you need to start (luxury can be considered later)

strop choises hmm ruprazor the Filly is a good start or Illinois strop of ebay
SRD and some other more exspensive strops lets you order replacement leather
so the cost of wrecking it wont be much different

For soap id suggest Tabac (seems to be werry easy to use)
I belive it is cheapest on fragrancex.com but if your not in US the wait to get it can be long
