There is also a Gel extraction purification kit, which would be more useful than the above, as it allows you to purify PCR product of different Kb- http://www.lifetechnologies.com/order/catalog/product/K220001
Manual method is mostly the Gel elution technique, wherein you run the sample on low melting agarose, slice out the band of interest and proceed with melting in Low Melting/ Salt buffer, Phenol:Chloroform washes, precipitation with Isopropanol and resuspension in sterile distill water.
Although not identical to your question, you will see that the answers are similar. In other words, there is rarely a "best kit", but rather just many opinions. I do not know exactly what you are looking to do (maybe just Sanger sequencing?). If so, it is likely no purification is necessary. You could just treat with Exo SAP IT
