OK, I have just read (almost) every thread on this forum going back one year and did not see this question posted yet so hopefully I am not repeating anyone.

I recently purchase the Sony alpha 350 with a Tamron AF18-250mm F/3.5-6.3 Di-II LD lens. I already own a cheap (bought at Target) tripod.

I know I need to purchase a few more goodies before my trip to Ireland and I want to make sure I have everything before I go.

I am thinking of purchasing the Sigma 10-20mm f/4-5.6 EX DC (if Don is happy with his) or a similar lens, and then I will also need to purchase a flash.

Can anyone provide some recommendations for a wide angle lens? A flash? A tripod? Is there anything else that I will need? I am somewhat new to photography and I want to make sure that I get the right equipment.

Thanks in advance for your help.
