This sounds like a perfectly fine plan to me.
I do the same thing as cybrsage ... not sure about the rules on posting which vendor. For supplies, I like the BD - 305193 23G x 1 in. (Thin Wall IM) or 305194 23G x 1 1/2 in. (Thin Wall IM). These happen to be thin wall needles that say they are specifically made for intramuscular injections (I think that means standard bevel but I'm no expert). Thin wall - the inner diameter is bigger without any increase in the outside diameter. The BD_Hypo_Catalog is out there if you want a little more information. They are not particularly expensive in boxes of 100. I find they work well. I also like BD 305195 18 G x 1 in. for drawing. Not a big deal, plenty of sources for these and others that no doubt work as well.
