I don't think the prefixes deter buyers. Startups have to start somewhere... and many will start it on a 2nd class name like this. When they make or raise money, they upgrade.
The problem is there are dozens of alternatives. MyRodeo, GetRodeo, UseRodeo.com, Rodeo.io, RodeoWord1.com, RodeoWord2.com etc... Plus I think "try" is one of the worse prefixes too because try indicates that it's temporary... like what do you do after you "try" it?
If this was my name I'd price it in the 2-3K BIN range. Maybe lower if I actually wanted to sell it.
Also this is just my opinion and I have no experience selling these kinds of prefix names. Maybe someone can chime in with more experience.
