These are definitely worth what you are asking. I hope you get it as Steve makes a great product. He made my 20 x 24 dip tanks. I have this size for my 10 x 12 work so I don't need them per se, but if you can't sell them at that price and are willing to part for 300 I'll buy them as backups. That price is about what I can afford for backups.
best of luck on your sell to someone other than me!!
