1) build quality - Rane makes solid, tank-like mixers.

3) resale value - when you decide to upgrade, a Rane would still command a respectable amount of money in the open market.
4) servicing - It's a US-built mixer by a US company that still refurbishes all their products if you need some work done on it. Some companies don't repair their gear and the few that do, you'd have to send them out of country (not cheap).
All that for only $50 more.
Yes, it does appear to only have a two-channel EQ (it's a turntablist mixer). That may, or may not, be that big of a deal. You'd have to decide how much a separately controllable 'mid' EQ is important to your mixes.
I hear your concern about the infrequency of your gigs and the audience not likely knowing the difference... but if that's the case, then why not just use your current Stanton mixer? That way you could save up money. $175 + tax/shipping (roughly $200+) would go a long way towards the purchase of a higher-quality mixer in the future.
Ultimately, I just don't want you to make the same mistake that most of us here have made at one point or another. Some of us (like myself) made the mistake of buying a cheaper mixer because we were just too impatient to save up longer. Some others make the mistake of buying cheap turntables instead of Technics 1200s (luckily, I made the correct decision in this case - I still have my original Technics turntables). My first mixer cost about $400, which was almost half the cost of the going rate for new higher-end mixers at that time ($800 - $1000 back in the day). It lasted about a year before one channel started fuck up. Then the crossfader started to bleed sound. One knob also popped off all the time. It was at that time that I realized that I should have listened to those who warned me of wasting money on a budget mixer. Live and learn they say, but this is a lesson you don't want to have to learn the hard way.
