A quality patchbay is going to be your best and cheapest bet. If you think that's too expensive, you really don't want to start looking into consoles. Figure out how much you paid for that Mackie (probably more than what a cheap 1/4" patchbay is going to cost you) and since you're already complaining about the sound quality, imagine what something that costs less will sound like.
Good quality audio is an expensive endeavor. If there were ultra-cheap products that sounded like the really expensive ones we'd all have fatter wallets.
