D'Adarrio strings...$3/set if you buy them in groups of 10.
I use 9-42's but I do a lot of string bending..pedal steel licks etc...so I prefer a lighter guage.
Korg tuners. I have a new Korg tuner now, but I still have an old one...a tuner that has been dropped on concrete numerous times, and had beer sloshed all over it, and been put through all kinds of abuse...it still works like a champ.
The only reason I purchased a new Korg was because the newer ones have hands free tuning. My old Korg had a switch you had to move to tune each string.
Korg tuners, and D'Addario strings come with my highest recomendation.
