I don't think you'll be able to check the wiring/shielding etc of the guitars. Doubt any shop'll allow you to unscrew the pickguard/control cavity plate to let you examine.
Unfortunately, thats true. Shops wouldn't let you do that so you'll only find out the truth when you buy the guitar. But you can listen to tell tale signs of bad wiring... strum something then listen for crackling when you move the volume or tone controls. Switching pickups shouldn't have too much noise and each position of the pickup selector should give you a distinct, clear tone (e.g. Neck sounds mellow, bridge sounds sharper...).

The physical things you can look out for, mainly neck warp, overall condition of the guitar. Possibly listen carefully to the sound when plugged in, whether theres hum or crackles where there shouldn't be any.
Yeap, a physical check is the best you can do.... pooo has listed out some stuff... here's somemore things to check if you are getting a better quality guitar and remember, you want to upgrade from your current axe so you are comparing to your current axe.
1) Check the finish esp at the neck joints. You'll know poor finsihes when you see them.
2) Frets (esp > 15) should be smooth to allow smooth vibrato but at 300, don't expect too much.
3) Quality of tuners. Cheap tuners do not look anything like them branded Gotoh, Schaller tuners. And they don't hold tuning well. Maybe do a few big bends, then check the tuning. Do it a couple of times. If the tuning runs after a couple of bends/retunes, the tuners are unstable.
4) Check the Bridge. The bridge should look well constructed and smooth, no rough edges where the strings go thru/over. If its a trem, try to use it and check if it can flutter well.
I know that some of the above check are going to be definate fails for a $300 axe, but well, if you really want it... :roll:
On the other hand, why don't you fork out another hundred or so, and get the Yamaha 112 series guitars? I saw some today and at roughly $450 for the Pacifica 112XJ (or something), it's built rather well with a nice matte natural colour (Body is alder) finish to it. Fretboard looks smooth and nicely filed. Trem looks like how a vintage trem should look... and it has a h-s-s config with a 5-way switch, versatile enough!
If you really want to upgrade to good stuff, sometimes, you just got to spend that little more and you'd be rewarded with a good playing axe! 8)
