That would be the wisest! I'll wait until I have some cash and do the same - a few matched achromats, few different achromats, some meniscuses and so on. I heard something about getting to use a 3D printer and maybe even a CNC machining center in the university if I behave good enough, so that solves the issue of barrels for me.

I wish you good luck on your endeavors! Keep us posted with the results!
