Good price for a B2620

[Arth]

Hi Folks,

I'm looking to buy a B2620 in Northern VA and received the following quote:

B2620 HST
Loaded R-4 tires
LA 364 loader
RCK60-29B 60" mid mower

$18,400 (pre tax)

Does this sound reasonable?
Would you purchase the rear remotes with the tractor or add them later (I want to add TnT)?

Thanks!
