Who has the best prices for Do-It jig head molds? Have seen this info posted before but can't find it now. Also, are there any problems with not using a wire insert in a mold designed to use one? -just don't want to spend a lot of time cleaning up any "leftover" lead or holes where the lead did not flow. Am considering the Do-IT mold with 4 cavities for 1/32 and 4 cavities for 1/24 heads with the wire insert-just have no need for the insert. Many thanks!
