Im in a similar boat, Would love a hudy setup station but cant bring myself to spending the money on one.. I have always used calipers and camber gauge ect.. and the other week plopped it on my mates Hudy and WOW was it seriously out.. specially toe on the front!.. But, I reckon if you know someone that has one.. you can borrow/use once in a while.. thats good enough. There good, but A few crashes and its becomes off anyway. Alot of it is in the head..I mean..confidence There nice and useful but not worth the money..
But that's not to say if I had loads of dosh to spare wouldn't get one..
