We bit the bullet right at the start of my goatkeeping - a proper portable goat milker which even 10 years ago was over a 1k, BUT - it has never not started, and so far works like a dream. No point in trying to buy cheap... and it means my husband (who never mastered handmilking) can do the goats without any problems as well.
Looking at the teat sizes of my Shetlands - no I do not want to hand milk them! Even my lambs that need colostrum usually get frozen goat stuff!
I also had CTS (operated on a few years ago and no problems since) and now arthritis in my wrists, so handmilking more than a couple of goats on a daily basis is just not possible. If you want to continue to do serious smallholding with bits of your body failing - and it happens to most of us once we get to 50 - then you need to invest in some proper technology, at least it is available these days!
