There are a fair number of Cubs here in Maryland, and up into South-Central PA. This is fertile, but rolling country around here, and it used to be an area of lots of small dairy farms that have either been broken up into large lot homesites for those who want to live on the fringes of suburbia, or converted to other agricultural uses, such as tree nurseries, vineyards, and small beef cattle or sheep operations. The large homesites and specialty and Gentleman farmers around here were a ready market for small tractors. Quite a few of the sons and daughters of the old farmers still live around here, and recognize the value of the old Cubs compared to the consumer grade stuff sold at the local Home Depot or Lowes, so they tend to keep 'em running.
Also back in the day there were a couple of very strong IH dealerships in the area that sold not only a lot of Cub Cadets, but also a lot of Farmalls from Cubs all the way up to the M series. Although the area is turning Greener(as in John Deere) there is still a lot of old IH equipment around and still running, and a decent Cub Cadet dealer nearby. There are also quite a few old tractor and engine shows in the area each year, which all have pretty decent flea market areas to find what you need as well.
Sounds like you got a good handle on the S/G as well, save the old parts, you never know what you might be able to use off of it in the future.
