3 years is too long for me for any build, but some people do choose to wait!
ACG made my last bass - it was half the price of a Wal and was built in 9 months start to finish all by Alan himself. While 'the Wal tone' is unique, my ACG is nothing short of spectacular and has a lot of excessive options too (buckeye top, camphor back, highest spec pups/pre, set neck etc)
If you HAVE to have a Wal, then you pay up and you wait, whereas if you want an exceptional instrument for far less money and far less of a wait then there are certain other very very good options to consider.
