I bought one from Bud this spring.
I had the same advice - to provide him with measurements ... then Bud told me he doesn't do that anymore.
The website is right, and the suggestion to call is also right - I think e-mail might be a once-a-month thing.
The trailer I purchased for my GT150 is awesome - I had to re-do the bunks and bow rest (it was too high for this low profile boat).
I paid $575 in the spring of 2013, trailer was a 2012, never titled, still brand new. It came with swing-away tongue, retractable safety cables, and guide-ons (which I didn't think I'd keep - but they aren't in the way, so I'm leaving them where they are).
