Any DIY'er should have test equipment. A good used analog scope can be had pretty cheaply these days. My previous workhorse is a Tektronics 2215A, a 60MHz dual trace I picked up for $125 through an add in the local paper. For analog work you really dont need a lot of bandwidth, so any dual trace with 20MHz or more is fine. You should be able to get one really cheap. If you want to go modern, and get a DSO, they can be had for as little as $300 or so. Go with Rigol, Siglent or Owon for a low cost solution. For a signal generator, again used is fine, or new ones can be had for $100 or so. You can get a brand new B&K Precision 4001A from Allied for $200. Look around and find ones that fit you budget. Once you get used to having it, you will wonder how you ever managed without it.

Tenma makes a nice and very low cost (model 72-505, about $40) signal generator that produces sine wave and square wave outputs. The sine wave is very low distortion ( < 0.05% in the range 200 Hz - 15 kHz), which is handy if you ever want to make distortion measurements on an amplifier.
