I am not familiar with the pricing on the attachments, but the price seems high to me, even for North Dakota.
My L4630GSTC was 31200 with the loader, QA, bucket, three remotes, radio kit, rear windshield washer, draft control, block heater, rear work light, including prep and freight, and ag tires. This was in November of 04. There should not be that much difference in the price of the two tractors. Remember that I have the cab model.
I purchased mine in Mandan and had to work them on the price based on the pricing seen on this forum. At the time I paid a little more than others on this board for the same in a 5030. Chalked that up to being in ND.
You might want to check out TSC on the attachments, have been happy with mine. /forums/images/graemlins/grin.gif
