Just a heads-up that Rokcet Scientist's linked video may not be appropriate for viewing at work or by younger viewers.
Also (and not to disqualify the software suggestions -- while I haven't used PhotoLine, those other two are great apps).. a single-user license for Tiger is only $129USD and offers a ton of great and useful features over 10.3. Buying licenses for those other three apps would run you ~$255USD.
Granted you're running non-beta software in the end, but considering you're now looking at moving between 3 apps instead of one, are $120 lighter in the wallet, and miss out on some of the tremendous tools Tiger brings to Our Kind, I have to say my vote goes to Tiger+Lightroom.
