I must admit to being continually disappointed by many "made in the ROC"
products, due some plain dumb engineering, poor QC and short longevity
(read: gentle puff smoke escaping on power-up)
I have
one of these on my 130GTX. It's been ticking away for 7 years without a glitch. (It's interchangeable with my AP155 focuser)
and it didn't cost $1k....
