Best windshield replacement services in the VA/MD area

Time has come to replace my windshield (98 chevy cavalier), I don’t feel like driving around any scrapyards so I definitely want them to come to me. Right now I am looking at:
http://www.crackedwindshield.com/ they say it’ll be like $200
http://www.autoglassnational.com/ say they’ll do it for $250
Anyone ever use these guys? Are they reliable? Know of any better ones?

Just a thought: It might be worth getting some recommendations from your insurance company. They probably know who does decent work at a fair price. And even if they’re not paying for the job, the insurance connection gives you some leverage if there’s a problem (if you say “state farm sent me,” the shop will probably try hard not to get kicked off their “approved” list).
