Hi Paul,
Here are my suggestions/opinions/comments
1. How long do you plan to take to complete a set (for T206 shall we assume the typical 520 card set)?
2. What grade range are you shooting for?
3. What is your budget? ($10/wk, $50/wk, $100/wk, $500/wk)
4. How many hours/week do you have available to work on these sets scouring offerings on the BST, ebay, on-line auction sites, etc.
5. How well can you stay committed to a big project like this? It is so sad that too many collectors start fast, flaunt every pretty T206 Bauble they acquire, update their Monster Number three times a week, and burn out half way there and start selling off
With a budget of $300/wk, and spending a couple our 2-3 times a week on the internet, you should be able to pick up most of a 520 card T206 set in VG condition in about 3 years
Best Regards and Happy Collecting
Craig
