Hi Torq,
When your finances permit, I strongly encourage you to consider upgrading to the UltraPak. Once you've done that, it only costs US$99 each year to add all the new features and maintain the UltraPak from year to year. While I can't promise that this will be the case next year, I can say that this has been happening for around 12 years now. The UltraPak has everything (apart from bonus material) and it's the most popular package used.
Also, if you purchased packs from PG Music that require the UltraPak to work properly, you can ask for a refund if you are not happy and if it's within 30 days of purchase.
If I'm reading PG Music's pricing properly, you should be able to upgrade your previous ProPak (2017) to the UltraPak for US$169 during the specials. Since you paid $49 to upgrade you previous ProPak to the 2021 ProPak, you could ask for this to be refunded. That now brings the price of the UltraPak down to US$129.
I'm not sure if that's helpful information or not. Please note that I am not PG Music staff and I do not get paid anything to sell their product.
Regards,
Noel
P.S. Depending where you live, taxes/duties may be involved that will also add to the cost.
