MACHZE, I don't know what the prices are in other places, but Carver Equipment has their prices listed. Have a look at their web site. Right now they show a B2410 at $11.970 ($14.990 with front end loader) and the B7500 at $10,000 ($12,450 with front end loader).
The numbers in md are running the same as everybody else. as for is there a dif. well between the 7300 and 2410 it is night and day. other than the power steering there is a better seat, and i have yet to bog down when mowing grass. unfortanutely grass grew like crazy and if i wasn't out there ever 4 days the 7300 didnt do that great of a job. i have yet to regreat spending the extra cash on the 2410. my dealer was great! he let me try the 7300 at the house for a week! no charge.
