Believe me, I loved my old Pace unit too but it was at least 20 years old and was starting to show its age. I had to make a diaphragm out of some plastic to repair the vaccum pump last month. The heater is no longer available so when that one goes I would have been on the creek without a paddle.
Yes, I love this thing already. Its alot of cash to drop on something but I know it will pay for itself just as my old one did. I also splurged and got the higher end unit with the handpieces to do surface mount stuff. Im going to start learning to do some SMT work since there have been a few occasions where I needed it.
I buy all my pace stuff from marks electronics. Its up around DC/college park area and is only 1.5 hour drive for me. The lady that works the sales counter has worked there for 37 years! She really knows the pace stuff well and is very helpful when I call. That place is an excellent example of old school customer service, cant beat it.
