ok, finnally I got a 5L jag Elf DID myself

from Euroline Performance. http://www.eurolineperformance.com/
This retailer was referred by autocamping.ca Mississauga office. One jag plus oil filter cost $50+tax. I think it's a pretty reasonable price. The guy I talked to was pretty knowledgeable. He said he would get elf 506.01 shortly.
The retailer is on my way home everyday. Well, not exactly on my way, I have to exit QEW and take about 2KM distance. But it's very convenient for me. Anyone interesting in it, let me know. I can get it for you.

I play pool just down the street from there

I just picked up Oil, Oil Fiter, Pollen Filter, and Fuel Filter... all for under $130 (Taxes inc)... that is pretty reasonable. the dealership wanted $55 for just the oil, $50 for the fuel filter, $12 for the oil filter, and $40 for the pollen filter. That is $172.50

Gentleman at the store was very knowledgable and nice. I highly recommed Euro Line
