Don't be shy to check craigslist either....ive got some really good deals off there...not to say you shouldn't be extremely cautious if you do, but it can be a good source of good deals.
Also w/the griots...they offer a lifetime warranty. I think you'll be happy with it for a first polisher that will last you a long time im sure. I got mine for like $99 new from tooltopia. If you get pads, honestly the best ones ive used so far is the plain ole 5.5" LC Flats. Now that beign said i really wanna try some MF pads like the ones Meguiars just came out with. I have some surbuff but havent tried em out yet.
For the Accura...for CARS I usually charge $70 for wash/clay/wax tires/rims cleaned..tires dressed and interior vacuum/wipe down and dressing on the interior surfaces.
If you have a leaf blower it can save you a lot of time after you wash/clay...it helps get water out of the cracks between body lines...i love using my shop vac/blower in one

.
I did an Accura TL...i THINK the same year as well...about a month ago...it included a single pass polish and a full interior.
