I personally would think based on the L3301 pricing of approximately 22,500 I have seen (with HST, FEL, BOX, brushhog, trailer) that you could get the 2501 with a FEL for around 16750, maybe a little more. maybe even with a few additional accessories.
I would say at 22,500 with all the attachments and trailer you could remove about 1500 for a trailer, about 500 for a box, and about 1000 for a brush hog. that would put that 3301 at about 19,500 for just that tractor with FEL. so I would think 2-3k below that would be acceptable for the 2501.
there is a 2821$ MSRP price difference between just the 2501 and the 3301. take 2821 off the pricing I listed above at 19,500 and it puts you around 16700
keep us posted on what you find and actually get for pricing and with what options, this helps inform everyone.
definitely get the wheel spacers and beet juice in the rears worked in there at a minimum too.
