I only got enough cash on me for one. And that's the one with out momentum and braking. And I hafta hide if it from the 'wife'. Or she'll kill me. But only after she threw out the Tech II.
The Tech II power packs you asked about are the exact power packs currently in use on my under-construction layout. I have been very happy with their performance - they even handle catenary motors powered by two 60s-era open-frames without a hiccup.
If they are, in fact, on clearance, grab them quick, before they get away!

The LHS has a pair of older Tech II DC power packs, one's normal the other is 5 bucks more but has momentum and brake control. If I find out these work (they where in what appeared to be the clearance isle) are they worth getting? Doing a small computer desk layout, DCC is too much, trying to do it on the cheap and it's either get one of these now, as in today, or wait a few months when I can spend 50 bucks on a new Tech IV or RailPower 1300.
