I had a few PRO-2004's and at the time, they were the BEST!
I actually paid full price for my first one or two of them.
I modified ALL of them!
Then I started buying the PRO-2006's and they were even better.
I paid full price for the first one or two them also.
I forget what year they were closing out the PRO-2006's. Sometime around 2003 maybe.
I bought a LOT of them at closeout for around $150 or so. Maybe even less.
I built a lot of CE-232 interfaces of the Bill Cheek type and I wrote a number of programs for him. (And me.
)
I modified ALL of them too!
I had more than 40 PRO-2004's and PRO-2006's and didn't think I'd ever need any other scanners.
(I still have a few dozen of the PRO-2006's on the shelf. I gave a bunch to friends who were just starting in the hobby.)
Then........................
I got my first Uniden BCD396T when they first came out.
I loved it.
So ...................... I started buying a lot of Uniden DMA scanners. (BCD396, BCT15, and BCD996 of all vintages.)
I was watching Ebay every day and when one was in my desired price range, I bought it.
Today I'm running more than 40 Uniden DMA scanners of several vintages and the only thing that will make me change, is if I need some digital modes that they don't receive.
