I personally don't think it's worth it. It's gonna take you a lot of years to save up on minimum wage for boost anyways, so you might as well start off with a better platform for boost. You can have a B18A complete for probably around $1200 (if you install it yourself), which isn't all that much, and you'll already have a 140/130 base which seems like it was built for boost. Don't go wasting your money on another D block now, especially if you aren't making a whole lot of money. Just be patient and save.
