I was quoted $350 to have my Bronco done at a local tint shop. $254 seems like a bargain for a crewby. But as mentioned above, shop around.
As far as I'm concerned, go with the shop that gives you the best price and seems the least sketchy. If a shop says they'll meet or beat another shops' price, chances are they're not that good of quality. Ask around among friends, co-workers, etc. Word-of-mouth reputations are worth their weight in gold, in my opinion.
Good luck!
