SO I took the plunge...........and bought a PA. Wharfdale PM500 with twin 10's with mic and all the cables........R3200. Also splashed out and bought two heavy duty stands for the speakers for R300 a pop and lastly a mic stand.......R150.
The deciding factor was buying our works PA PM600 and damn that thing had grunt, I used it only to find out that 3 of the channels were crackling badly and a speaker had cone issues........so that was promptly returned. Fair enough that they did have it for the last 8 years.
A titan 12 would cost about R3400 and then I'd still be down on mic, cables etc, but I would be able to use it at a later stage. This option however is good for the gig room and allows us to play around a bit. The next plans are to make a rack for the PA that will have enough storage space for the 2 speakers underneath and all on wheels to make moving stuff around easier.
Thanks for the input guys and also thanks to my wife...........birthday came early this year.
