I am in the process of setting up an online store. This is the first project I have attempted which will require a good level of security, so I recognise that an decent SSL certificate is a must. My current (albeit admittedly basic) understanding of the options are:

1. DV SSL - more or less pointless, as provides no verification.
2. OV SSL - better, as provides a basic level of organisational verification.
3. EV SSL - 'better, full' verification, but much more expensive.

As this is a new business venture, and budgets are tight, which option provides the best bang for my buck?

I have read questions such as EV SSL Certificates - does anyone care? which suggest that EV certificates are a bit of a con. Does this mean that OV certificates offer better value for money, especially for new businesses with shallow pockets?
