Sandy, FWIW I use a Noblex 135UC, which I've had for a couple of years and it has proved very reliable. The small amount of lens shift I find very useful also the multiple exposure feature.
What can be a little problematic is the mechanics of the slower exposures. For example, for a 1 second shutter exposure the whole process of lens movement takes approx. 1 minute to complete. Not too encouraging for that 'decisive moment'
Like you mine was also a bit of a compulsive purchase but one I can honestly say I've no regrets. Enjoy
