Expiring May 13 (MIR), Home Depot has their 53L selling at $149, but with a $50MIR. http://www.homedepot.ca/webapp/wcs/s...k=P_PartNumber
I'm not sure whether it applies chain-wide, but the HD on Highway 7/Young is confirmed. Right under the display, there's a MIR form, exclusive to the WD1450.
I was planning to purchase the tiny one that Picus posted, but I'm a guy, and "Bigger = better" got the best of me. Comes with a plethora of tools too, and standard with a 2.5" hose(standard size for the accessories; any other size requires an adapter).
