Strings, this is one of the top 3 questions on the Deering FAQ. Here is what they say:
The most common gauge of strings used on any Deering/Goodtime/Vega banjo is our private label factory light gauge strings made for us by Dunlop here in California. The gauges are 10,11,13,21w,10. These lighter gauge strings will give the banjo a wonderful sparkle and liveliness and because they are not too heavy, they are easier for most players to manipulate with success.
The website currently says that their strings are produced by GHS, despite what the FAQ says.
Stick with the standard "light" strings for the Goodtime.
A new set of strings from Deering will cost about $8 -- they have a video showing you how to change strings.
If you go direct the GHS, you will find a lot of choices (Deering has a number of interesting choices as well). The Prices from GHS are $5.14 per set.
Of course there are a myriad of choices and opinions, one fellow says:
On my deering sierra maple I use mapes nickel steel in 11, 12, 16, 23, 11. Clear as glass and powerful when needed.One guy says he finds a good price and buys a dozen sets at a time.
So, I took matters into my own hands. I unscrewed the metal Y shaped piece, pulled off the rubber tubing and caps and
clamped it in a vise. I measured the inside spacing before I started: 2.65 inches. I used a short piece of pipe
to bend the Y shaped yoke wider. I got it to 2.82 inches (measuring at the ends of the Y). I put the rubber back
on and voila! Perfect!! I can now present my banjo straight on, and both of my complaints are solved.
It took about 10 minutes and no animals were hurt in the process.

Deering has maintenance manuals available for download on their website.
