Thanks Plattus1000. Wow, $4k. Ouch! I figured it might be around the $3-4k mark...definitely needs to be considered when buying one. I think I've seen your 4.6is on another thread - a beautiful black one, in Washington, right? Looks really clean - but yes, if you've already spent $12k on it in the last year (double ouch! Should I be reconsidering getting a 4.6is...?) then you probably want/need to get more than what my budget would allow!
