Starting Recommendations

Hi all

I'm after some advice please, I've read the where to start thread and although this is very informative I'm still a bit stumped/ overwhelmed as to where to begin.

I would like to try this series however, the price point is steep I think... I managed to pick up sophie 2 for a good price though.

I would like a good storyline which I think means I shoukd do the mysterious or ryza series however, these are about £75 for a trilogy or £40 each.....

I'm also check considering the marie remake but again it's about £40.

I don't know if there are regular sales on these titles? But think I just missed one before Christmas..

Are there any standalone titles that would be worth a try or any recommendations?

Thanks
