You have to look at the cost basis per tub on any rack you get. About any V18/V35 rack I am building has a cost basis of about $9- $12/tub with heat tape and tubs.

Most all commercial racks have a cost basis of $20- $25/tub. 16 tub V18 rack is $360 with Dragons4you and that does not include heat tape. Thats $22.50 per tub with no heat tape. Ouch!!

Three wide 60 tub V18 rack build in progress. 2 sheets of 1/2" XPVC (19" x 23"- factory cut to size for free)= $196, 60 V18 tubs= $255, heat tape= $100. Misc materials= $50.

Total is $611/60 tubs= $10.18 per tub.

Four wide 80 tub rack comes in at $10.42 per tub.
