What has been said above. I looked at the various packages offered by vendors such as MM and Griggs. Most offer the same parts individually so the user can pick and choose and/or build according to budget. Buying piecemeal is not cheaper but it will allow a long-term build-up as budget permits. If a package component is not necessary for your particular needs, it can be skipped. Moreover, in many cases used components or those where a guy "changed directions" can be picked up for less than the new price but are virtually "new." I can't say enough about MMs customer service; those guys go way beyond.
