The cheapest way for you to go would be to buy the 4.9 PFXXX small cell frames from Mann lake. You get regression rapidly. Then if you want you can just plug in foundationless frames and or, cut the inside of your plastic frame out and let them redraw it if you want to be that silly. The plastic frame gets all covered up with wax and no plastic is touching your honey or bees. Just so much simpler. I use a lot of them and they are just fine.
