There's always getting an airsoft replica to save on money. You can get a Vltor MOD/EMOD for around the same price as the MOE stock.
If you want a wide comb there are options for that as well. You can get a CAA saddle for the normal stock, SopMod stocks, Magpul ACS, Crane stocks, Vltor models, etc.
I've been debating swapping my MOE stock out for something with a wide comb, just haven't found the right deal yet.
