Depending on the price of rims and lugs it’d possibly just be cheaper to buy 10″ and 12″ toms and cut them in half to double the yield. Most come with lugs and hoops on both sides so one tom could yield 2 drums. I’d be curious to know the total cost of buying PVC, hoops, and lugs to create 6 full drums which is how many you’d need for a 5 piece kit. Then note you’d still have to buy/build a rack, mounting hardware, cymbals, stands, yadda yadda.

Not knocking the PVC drums. Just asking for some total cost estimates for comparison to buying a used kit or toms and cutting them.
