You get flexibility in your purchases and the correct lamps on hand if you do swap ballasts. T5HO ballasts will also run T5NO lamps, at a bit over the rated capacity. Not over driven to HO output though.
If you need a source of inexpensive lamps, check out your local hydroponics store. They sell more T5HO daylight lamps in a week than most fish shops will in a year. They purchase in bulk and usually sell at good prices.
