I'm also on the look out for a used hard-top, ~$2k, because Jerremy said I can't run DP without one.[/b]
James,

Are you planning to run Nationals in DP? If not, come on up to SFR and run in ITE without the hardtop. SFR isn't offering DP in regional races anyway (or more specifically, DP cars are explicitly invited to run in ITE.)
