I don't know if anyone still looks at this forum, but if you do, this was posted about a year ago.

I just received my canopy from parkflyerplastic and I must say I'm pretty impressed. The canopy was $8.00 plus shipping. The canopy frame was highly detailed, and it even has the marks to show where to cut the canopy out. The only disappointing thing I can say is shipping speed, but if your not in a big hurry, this place is well worth looking into.
Also if you need a cowling I understand fiberglass specialty is the place to go. I believe the cost there is around $30 to $40.
