The l3 by specs is twice the size of the F2 and an N_R5_50_52 is 50% larger than the l3. So you will have a good jump in size even with an R40. You will find the rotary much easier to maintain and easier on the grain for a higher quality sample. Personally I would look into a 5_50_52 as they are more common than the 40. The 5_50_52 also will handle the larger heads and higher yields better. Similar case when IH made the 1420, few sold and a limited machine. I run a 6 series and am very pleased with the performance of the machine.
