That is odd … and no free shipping to Canada? One thing you have to note is that the shipping charges are a technique by vendors to get their product listed. What you need to look at is the sum of the item price + the shipping charges.
As far as a dispenser for VHS, I think I’m going to order this one tonight:
It’s cheaper ( by about $20 USD) and the only difference is that it uses an analog control to adjust the dispensing time instead of a digital control. From the documentation that I have found, both the AD982 and the YDL983 have the same accuracy (±0.05%) and same precision ( as low as 0.01 seconds ).
Also note you’ll want to get an air filter for the compressor line ($5 at Summit Tools from memory) and you may find the air coupling on these a little challenging. I took one from another tool and adapted it to the hose.
Finally note these are all 220V units, I converted mine to 110V easily, YMMV. Am happy to help.
