It might depend on how active your DIV league is, but if you expect to finish in the top four record wise I doubt it is worth it to spend a lot on scouting. You will be scouting very nice prospects you will have very little chance of getting. Just save the money on scouting and get a decent prospect off the transfer list. Maybe you get lucky in the draft and hit the jackpot anyways. This year I cut back on my scouting. I got what I paid for with all 3 picks being 1-ball potential. There were 3-4 nice picks out of my draft, I think only one went after my pick (14th) so maybe an extra $10-20k a week in scouting gets me that guy, or I can just buy a decent 3-ball potential prospect with the $150-200k I saved over the course of the season.
When I promote up to DIII (who knows when) I will start investing a lot of money in the draft looking for that million-dollar prospect. But until then, I will develop my current trainees, expand my arena and work on upgrading my team. Scouting can wait.
