Miata coolant/heater hoses

The hoses on my '90 have seen better days. In the very near future, I need to change all of them. Upper, lower and heater hoses.

I've seen hose kits from Mazda dealers for about $90. Is that the best way to go? I've heard some of them are a pain in the a$$ to replace. Knowing that, did anyone order from Rock/Pep/Autozone and have fitment issues where you wish you had just ordered from Mazda? If you did order from those places, do you recall all the part numbers (there are a lot and the pictures don't help a ton)?

I bought from the local auto part stores. I used a generic hose for the heater. The radiator hose was "one size fits none" and had to be cut to fit. They seem to work o.k., the only problem was the hack mechanic (me) didn't get the lower hose completely tight and had a small leak.
