I have used a Series III tonearm on a TD-124 and found it to be an excellent match, IF you take care to mate the proper cartridge to this tonearm.
The SME 3009 Series III tonearm is quite different from the earlier Series II model. It is a low mass tonearm designed for high complance cartridges when ultra-low tracking force was de rigueur in the 80s. However, I find it to be an excellent tonearm with many useful features, including interchangeable arm wands and the ability to really fine-tune the arm for best performance.
As mentioned, this tonearm requires a high compliance cartridge. I have had good luck with the Ortofon 2M series - I have run the 2M black on a TD-124 and IMO it was outstanding. Also, most of the Soundsmith cartridges can be ordered as 28 uM (high) compliance units. Some other choices would include the AT OC9/III and 150MLx, Grace F9, Grado Gold/Silver/Black/etc series, Ortofon OM30, Shure V15 series (w/ JICO SAS), Sony XL-MC104P. Some of these are avalable new, some are via here or eBay.
Downside: I can't think of any LOMC cartridges that I would try to mate with this arm, but that's not a big problem in my book.
