You're getting some good advice here- forget Behringer or 8-bus anything for either of the applications you mentioned. For the money, Mackie will hold up better and sound better than anything else in its price range. The 1202 is, IMO, a notch too low for recording or live use. I would never buy a mixer for anything but "set and forget" applications that uses rotary knobs for level setting.
The 1402 VLZ gets around that for a little more money, and one of the two aux sends can be switched pre or post, meaning it comes out of the mixer either before or after the level faders for each channel. For a monitor mix you need pre-fader signal, so you can change the main mix without changing the monitor feed. For effects, you need a send that changes if you change a channel fader, so you don't end up with full reverb on a signal you just faded down or out.
Yes, the 1402 can be used for recording - add at least $2000 to the price if you want to do it (noticeably) better. Here again, there are two main reasons for moving up from the 1202, not including better routing capabilities - Faders instead of knobs. Picture trying to mix a song from either tape or DAW, with multiple inputs to the mixer, and you need to raise the levels of two stereo channels while simultaneously lowering the main out so your record level for the mix remains constant (listening to the stereo out, of course) - With faders, you grab all 4 channel faders with your left hand, fingers above and heel of hand + thumb below, and slowly push all four faders up while listening/looking at output meters and simultaneously lowering the main stereo out faders with your right hand - Care to try that with knobs? Care to look at the board for 1/2 second and tell me what all your levels are set at? Didn't think so...
Anyway, here's a link if you haven't already looked - you can put the extra $300 toward vocal monitors or power amps.

Another option, more for live than recording - bang-for-buck, if you already have (or need two) power amps to run separate monitor and main systems, is a "powered" mixer. Some sound crappy because the added drain on the power supply affects the mix quality, but I've had good luck in the past with Yamaha powered mixers. The EMX-3000 would give you effects plus an extra stereo power amp, which in a pinch could be used as two mono amps, one for mains and one for monitors. Routing is flexible enough to patch things where you need them, and it's all in one box. This wouldn't likely be quite as clean for recording, but still usable. Powered mixers are normally used when the mixer is either on or close to the stage, since long speaker cable runs are best avoided for several reasons. Here is a link to the Yamaha - if I were doing this on a tight budget, I'd look at this option pretty close...

I'm glad you have horns in those 15" cabs, had me worried for a while... Steve
