here's a good link to some products from Rockler http://www.rockler.com/product.cfm?page=10562
Their CA is pretty reasonable-- probably not foam safe. good price But the neat item is the interchangeable tip package #67727 nice size selection tips 2 of each plus a 2 caps, easily removed and cleaned. you can add Teflon tubing for really fine tips, etc. I found it much better than the std hobby tips Tom
