I would recommend you try to find one with all hydraulic options and topntilt hitch. That is what makes them a versatile choice, being able to use a ssqa grapple without making modifications or hanging an auger on the hoe, having a thumb for the hoe. three rear circuits for a box blade or rear blade. After 12 years with mine I am so glad to have all the options. The Laurin cab has been a good choice for me too but isn't for everyone. I bought the 4520 cab after the 110 so that the implements could be shared and for the most part I could leave the backhoe on the 110 and still have a 3pt tractor ready to work. Keeping the overall weight of both machines low enough that they are easy to tow in the mountain terrain I work and live in made this a good choice for me. That said the 110 falls short on power for some of my 3pt work compared to the 4520 (60 hp.).
Kubota's are also great tlb's and the M59 and M62 with 60 hp. are almost perfect but still no factory cab.. If I had my choice I would like a full size tlb with removable hoe and cat 2 or 3 hitch with factory cab. So far neither Deere or Kubota have offered this.
If you are looking for a 110 used I would also look at the L45 and M59 models too all are good choices.
