Just this week I purchased a TC45DA with 16LA loader for under $24K here in Northern Cal. During my search, I also looked very closely at the Kub L4330HST with 853 loader. I found the orange and blue machines to be very comparable in size, weight, power, etc. Yes, the 45 has a sloped hood and curved loader arms, and the 4330 seems to have a quieter engine and smoother HST, but none of the differences changed my view that they ought to be worth the same price.
I mention this because, as I recall, the Kub list price with FEL was somewhat lower than the NH list price with loader, leaving me with the impression (valid or not) that I ought to expect a greater discount on the 45, if I ended up going that route. I did end up buying blue (the local dealer was far superior to the local Kub dealer), and I was able to get a sizable discount from NH's list price. I also pursued the L4330 purchase long enough to get the sense that I may very well have ended up paying about the same for the Kub as I did for the NH, despite the difference in their MSRPs.
That said, if you talk to enough dealers, you should be able to secure at least a 10%-15% savings (off of list) for a new machine. Harvest rental return deals, if they are available in your area, could push the discount closer to 20%.
