May as well put all the weapons up to 40/41 in the shop, along with rings etc.
No challenge, no achievement - however, I would counter that with the current way the server is, 40/41 is like 2001's level 22.
Just keep in mind you have to entertain them for 40-80 (or crazy rebirth or whatever) and make adjustments as they require them, not necessarily how you'd like them.
What happened to Mir being Mir ? If you want easy games, WoW came out to sustain all that.
As good as this server's engine is, I'd rather play on one that kept pace with an 'official' timeline, rather than feeding the masses their quick fixes. If you don't like Mir, play something else.
I'd hope this server works off the basis that if enough of something is sold to the shops, the shops will produce them - like in Mir.
