Vector drawing on iPad

I can’t draw for ^&$& but I’d like to know if anyone out there has found a good (reasonably priced) vector drawing application for the iPad?

I’ve found…

iDraw? [video ] (can’t give opinion, never used it) [import]uid: 95346 topic_id: 24309 reply_id: 100319[/import]

After much debating I have settled on iDraw, PS Touch and DropBox. [import]uid: 8271 topic_id: 24309 reply_id: 112128[/import]

if you can’t draw, how do you use the app? I’m curious. I really suck at drawing. [import]uid: 98393 topic_id: 24309 reply_id: 118893[/import]
