Analogue-sequencer

Hi Colin,
 
Firstly, apologies if you pick this up again in your email account 
(there's 2 messages in your inbox from me)!

Just wondering what, if any, Sequentix P3 parts are currently still 
available and their prices.  Also, to the best of your knowledge,  
how much would it be likely to cost me to build one, having sourced 
the remaining parts?
 
I guess the hardest thing to obtain a duplicate of would be the 
PCBs, am I right?  I expect most of the other parts (excluding the 
enclosure) would be relatively easy to find, although I've heard 
some of the ICs are a bit of a pain.
 
I ask all this since I wonder if it may just be worth my while to 
snatch one from eBay.
 
Just a thought - is there anyt other analogue style MIDI sequencer 
that has as much flexibility and functionality as the P3, in case I 
really struggle?
 
Just another thought - if PCBs are no longer available, I may decide 
to build or etch the PCBs myself by hand if that's possible (i.e. if 
the boards are not multilayered and tracks aren't too tightly 
packed).  Otherwise I could pay for them to be computer etched, 
price permitting.  Are circuit diagrams available?  The actual 
etching "masks" (is that the correct word?) would be even better, 
since I could just copy / trace them and etch from those.

Cheers & look forward to hearing from you,
 
 
James Jackson
