However, on the opposite side, if a template you purchase is suitable but some changes must be made to suit your site's theme, then you will have to take some time to make the changes. http://www.brandwebdirect.com/
For example, you can find a very nice template that suits your hobby site except the original designer has put an image of stamps in the header. You can find images of garden plants and spades to replace the stamps for your gardening hobby site. However, do only make the necessary changes and don't redesign the whole template.
