[casual_games] Trademarks - Registered?

[Phil Steinmeyer]

I did my own trademark searches on my company and game name at this site:
http://www.nameprotect.com/cgi-bin/FREESearch/search.cgi

I didn't see any conflicts.

That said, I'm wondering whether I should

1) Have my law firm do full trademark searches (at ~$1K/each)
2) Do full trademark registrations (not sure on cost, but probably $1.5K 
each if done through their firm)

Thoughts?
