Most sideshifts for sale are either in the same condition as yours or expensive. I sold two basket case trannys off to finance my Smitty conversion a few years back. Every time I opened one up I was at $2000 in parts. Now I can just go get a junk yard Toyota 5 speed, replace it's rear seal and pop it in. I won't even bother opening them up. I can get a complete Toyota tranny for less than the cost of balking rings, bearings and seals for a Healey box. As soon as you need a gear, layshaft (ouch!) or any other part for a Healey box you have just entered the financial pain zone. Unless of course you are rolling in the dough like Keoke. /ubbthreads/images/graemlins/devilgrin.gif
Keep your eye on eBay there is a fella who sells rebuilt ones but be prepared to pay about the same price you would pay to get a decent complete project Sprite.
