In the next couple of days i am taking delivery of our new line. They are digital power packs, which not only have extremely fine tuning control, but they also measure four major electronic measurements: SPEED, FOLLOW THROUGH, DUTY CYCLE, and VOLTAGE. These are not cyclones, or maybe they are, they just dont say it on them. Very smooth power which will not allow any stutter or voltage drop. I am offering a couple on here, and the rest on Ebay, unless there is more interest. The foot pedal is not included in the price. Cost: Â£44.99 + Â£4.50 UK 1st class recorded postage. Paid via Paypal. If interested, contact me.
