The key is though we all need to start somewhere and we need a reference point to compare different equipment to.
There are also drawbacks to a five year plan which is what I did. You never hear the potential of the products you do own until you are done. Manufacturers and models change as you build. Some of your equipment depreciates as you are still building although if you choose wisely its never by much. And before you are done there is a new format to compete with.
The advantages are. After five years you are further then you normally would have been. You have years to audition different products until you are ready to buy. Some of those discontinued models you originally wanted drop in price. You end up with an excellent reference point to start switching out new products.
I consider this hobby a life long adventure. I admit I enjoy the equipment almost as much as the music and I am looking forward to the next thirty or forty years of building and experimenting.
