Have you got a small amount of money every month to invest? Set up a standing order for 1500VP and you will be EA2 month after month.

That is a standing order for less than $50 and 4 hours per week of time. Any extra time can be spent advertising, reading at SFI,and bidding at auctions. You can do more if it is below your limit.
