I ordered a Solo Deluxe thru Leonards ($99+12.50 shipping no tax) with diaphragm pump, since I will be spraying WP (Captan) twice a year with it for my dogwood and apple trees.<p>Lawrence, your idea is good for open lawn areas, my usage will be primarily for semi-dwarf fruit trees on my property. The few lawns I will use it for spot spraying are all under 10k square, take out the house footprint and garden areas and actual lawn area is much smaller.<p>Thanks to you both for your suggestions.<p>Bill
