In my opinion SAB there are 2 main camps to this; either you go with a fixed line head (eg little juey) or you spring for a speed feed.
I would personally go for the speedfeed for around $20 off ebay
That being said, when you say homelite 25, do you mean a modern one? If so this is the least hassle to fit - is a quasi speed feed.
