pay to blog vs supporter revisited...

I'm concerned that you guys keep saying that Supporter supersedes Pay to Blog. They are so different and serve such a different purpose that I can't see why WPMUdev is making that call. I understand that supporter upgrade is coming, but I'm afraid that the Pay to Blog features may not be well represented in the upgrades.

Please consider in the making it possible to:
1. Simply pay to create a blog (using wp-signup not just the back-end)
2. Use text fields instead of drop-downs for pricing options.

Thanks
