From what I have heard the Well MB05 has not so good internals, and in my opinion should not be upgraded.
The UTG L96 is a great starter gun if you plan on doing no upgrades whatsoever. Yes it is possible to upgrade this gun, but its not a 100% clone. It has a tightbore barrel already and shoots around 460 FPS with .20's out of the box. So this lets you decide if you like sniping or not with a gun that can get you close to where the upgraded guns shoot.
If you are on a budget and cannot afford a TM, CA, etc. and want to upgrade your gun to shoot like a beaut then I would go for the JG-BAR10 (G-Spec if you so chose).
This gun is 100% compatible with TM VSR-10 upgrades.
