I think the pricing issue should not hold you back from trying new kits. If pens are priced to absorb the cost or absorb an increase then kits that are nice that might be an extra $4-$6. For example I sell a ~$17 Triton for $115. Adding a couple of bucks to the kit price in that scenario is not going to matter much. If it did I can increase the price by $5 and I doubt it would deter the buys willing to pay $115 for a pen.
From the other point of view if you are pricing that Triton at $35 to $40 I can see how that increase might affect you more.
I really don't want to get into a pen pricing discussion though.
I like the all metal parts of the new kits. When I first started with Woodcraft kits I was always disappointed in the kits that had plastic threads exposed. I like the all metal look better. I think I might have to get dressed and go to Woodcraft and try a couple.
