I use a mac computer so my experience of the various programmes is a bit limited but "Celtic Pipes" is probably cheapest and I found it easy to use. The website claims it can be used to write music for GHB's, tin whistles and drums and also import files in various formats like abc & bmw for example.
You can download a 30 day free trial from their website, worth a try.
We tried piobmaster on a pc a few years ago and it was ok but then the pc broke and we replaced it with another mac and so didn't really get a good go at piobmaster though looking back I think Celtic Pipes is easier to use.
Again I believe there is a free trial available.
My partner is a music teacher and she uses Sibelius which is fantastic but a bit pricey.
