BOS Booklet (Shen & Beynon) & CD Buying Advice, plea

[gailprentice]

I am thinking of purchasing some booklets from BOS Booklets but am not sure of the complexity level of all of them. I can fold intermediate level and would like to be able to fold advanced level...for geometrics right now.

Under consideration are:

- 18 Shen Selected Works
- 27 Beynon Origami
- 37 Beynon Origami 3
- 38 Beynon Fourigami
- 44 Beynon Multiplication
- 70 Shen Further Selected Works
- Brill's Wedge Flexicube (I can follow Sara's tutorial - so I assume I can manage this one - thanks for all of the excellent videos Sara!)

Do these have more than one or two good models each? The ODB has very few pictures of the contents. How hard are the diagrams? I already own Flexagons 11 but have never used it. Did I miss any other interesting geometrics/modulars booklets? All the others seemed to be for other types of models or very complex.

Also, are any of the convention cds worthwhile? Thanks in advance!
