I've only used one bottle of it, just following Ilford's times (and the Massive Dev Chart where the film wasn't in the Ilford documents) and had excellent results. Not particularly outstanding in terms of fine-grainedness, but I like the tonality and had reliable results with it.
Pakenham is not too far from Ottawa where I live. If you're looking for alternatives, I just picked up a bottle of Ilford DD-X from Henry's in Kanata. They had to order it in from their warehouse but it got here in a few days. Check their website, if it says "Ships next business day" it means they can get it to a store without additional cost.
Powdered chemicals last for years in storage - a big advantage. Ilfosol seems prone to sudden death in the bottle after a time.
1-litre packages of D-76/ID-11 will do you about 6 rolls of 135-36 or 4 rolls of 120 assuming you dilute 1:1, so it isn't hard to get through it fast.
Alternatively you can get XTOL, which although powdered, can be mixed at 20 C and used immediately. However, the smallest package is 5 litres.
I find mixing D-76 a couple of hours or so before you need to actually develop is good enough.

A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.
