Lochmaster is pretty good, the test button only checks out the circuit, handy to chk for leaks, HOWEVER
I would love to design some kind of project and TEST to see if it works or not, saves all the soldering/veroboard, and not to mention the crushing disappointment when you connect it to your power supply box and then ... nothing... 
Breadboards and me don't seem to get along, so veroboard was my next step,
Have been looking at Osil, Ocilis, Osily, Oscilloscope these big words get me every time, unsure if I need one though, the learning curve seems a bit steep, pretty new to whole electronic hobby thing, Doc tells me to keep challenging myself due to signs of Parkinson, Alzheimer's etc unsure which yet, but have always wanted to get into this hobby, but life never gives you much time, however challenge myself I will, just cant make it a long learning curve.
Veroboards I Like, have built a number of Kits, but would like to be a bit more creative, so any pointers would be appreciated.
Regards
Gary
